UNITED STATES WILLIAM C. ANTHONY, OF STREATOB, ILLINOIS.

Application filed December 17, 1925. Serial No. 75,926.

This invention relates to a burner, and particularly to a burner adapted to prepare for burning and burn liquid fuel. It has for one object to provide means for driving the feeding and mixing apparatus. It has for another object to provide such a driving means which is free from mechanical linkage and in which all mechanically engaged parts are outside of any heated zone. Other objects will'appear from time to time throughout the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawing, wherein:

Figure 1 is a vertical cross section with parts in elevation showing the burner and drive and associated parts in position in the heating chamber;

Figure 2is a vertical cross section on an enlarged scale showing the mixing or vibrating and feeding member with the drive parts.

Figure 3 is a horizontal cross section taken on line 33 of Figure 2;

Figure 4 is across section taken on line 44 of Figure 2;

Figure 5 is a detailed cross section on an enlarged scale taken on line 5-5 of Figure 2.

Like parts are designated bylikecharacters throughout.

A is a boiler having a base portion A sup ported on any suitable floor or foundation A. It is provided with a combustion chamber A.

B is a pilot light supplied preferably with a gas pipe B which is controlled by a valve B C is a vaporizer assembly. It is formed of a hollow generally tubular housing C which is connected to an impeller housin C which has a removable bottom C in whic is formed a cup-like oil retaining pocket C. Mounted within the member C is a rotating shaft D provided with an upwardly flaring central bore D and a laterally enlarged bottom portion D which is provided with a plurality of pick-u channels D which commue nicate with the ore D at or near its bottom.

At its top the member D is threaded and has seated upon it a cap E which is provided with lateral openings E.

F is an upwardly flaring mixing member provided in its bottom with openings F and iaving at its top a detachable cover F which is provided with downwardl depending spacing elements or parts F which are seated in a ledge or groove F adjacent the top of the cup F. The cover F is held in position by means of a bolt F which engages the cover and the cap E. Suitable anti-friction bearings G G support the member D.

H is a nozzle formed or communicating with a supply pipe H. It is designed to discharge a jet of liquid against the blades I of the impeller turbine, which blades are joined to a hub I which is fastened about the lower portion of the member D by'means of a set screw I J is a discharge pipe adapted to receive liquid after ithas been discharged against the impeller and dropped and fallen from it. J 1 is a valve in line with the discharge pipe J which pipe discharges into the overflow tank.

, K is a fuel supply tank. K is a supply connection controlled b a valve K which is itself controlled by a oat and lever assembly K These features form no particular part of the present invention and any type of supply tank may be used,

is a pump and in the form of the invention here shown a centrifugal pump is used. L is an electric motor adapted to drive the pump. L is a supply connection communicating with the tank K by means of which liquid is drawn from the tank to the pump and discharged into the supply pipe H which communicates with the nozzle H. L is a relief pipe controlled by a safety valve L.

M M are electric wires from any suitable power source by means of which electric power is supplied to the motor. M is a thermostatic time controlled instrument adapted to control operation of the motor and through it the operation of the burner. These features form no particular part of the present invention, and any form of such devices might be used without departing from the spirit of the invention.

The use and operation of my invention are as follows:

The rotaryassembly formed of the hollow member C and the cup F and the pick-up member D is mounted in the heated zone. When the furnace is in operation they are heated, but are to. some degree cooled because a blast of air is carried inwardly through the cup and into the burning chamber. When the burner is not in operation, the blast of air is discontinued or its strength greatly reduced and the heat formed in the combustion chamber of the boiler or furnace passes outward and to some degree heats the entire rotary assembly. For this reason it is desirable to have the parts so constructed that the action of heat upon them is as nearly neglible as possible. -For this reason the device shown embodies no mechanical linkage. Any expansion of the parts or the activating fluid, therefore does not interfere with the operation of the device because with the exception of the anti-friction bearings, no accurate fits are necessary and in the drive proper there is no metallic contact between driving and driven members.

When it is desired to operate the burner, the motor is turned on and it operates the pump which draws fuel from the tank and forces it through the supply system to the nozzle. It is driven under great pressure and at very high speed against the impulse turbine and thus rotates it at high speed. This, of course, rotates the supply and mixing devices D and F.

After the impelled liquid has struck the blades of the turbine, it falls downward and most of it passes out through the discharge connection. Some is always caught within the pocket C and is picked up by the pick-up elements D and brought into the bore D whence it passes upward along this bore under the influence of centrifugal force. After leaving the bore it is thrown into the inside of the cup F, passes up along it and is mixed with and drawn into the openings F and the combustible mixture of air and fuel passes out between the upper edge of the cup F and the top F and is ignited by the pilot light B and thereafter is burned. To some degree fuel is taken in directly through the bottom of the bore D which is preferably open and passes upward as above described under the influence of centrifugal force. The pick-up openings D are provided to assist in picking up the necessary fuel and bring it to the bore D where it can be acted upon by centrifugal force.
